The opening of the Ring gates creates unlimited possibilities for new adventures in The Expanse RPG and Beyond the Ring gives GMs all the tools they need to support stories like the novel Cibola Burn. The Ring gates are open, as The Expanse RPG advances its timeline to the fourth novel in the series, Cibola Burn. The Ring, a massive construct created by the protomolecule out near the orbit of Uranus, is a portal into a strange non-space known as "the Slow Zone." Centered on an ancient alien station, it connects to more than a thousand other portals to a thousand different star systems, each with one or more worlds shaped by the ancient aliens who created the protomolecule and intended to do the same to Earth. Now they are long gone, and vast frontiers have opened for human settlement and exploration. Beyond the Ring details the Slow Zone, Medina Station, travel through the Ring gates, and some of the many systems found beyond them, along with tools for Game Masters to design their own systems for characters to explore. Beyond the Ring opens up a whole new type of adventure for The Expanse RPG, as characters travel to distant star systems and face unknown perils!

As the pressure rises and the exodus through the ring gates continues, opportunities abound for shrewd crews willing to take risks on Earth, Mars, and in The Belt. The changes brought about by the discovery of the protomolecule continue to disrupt the status quo, and tensions between the factions are white hot. Sol System provides information on the governments, corporations, and factions that vie for power and influence, along with expanded rules for trade and running corporations and other organizations. For players, there is new equipment and technology, including cyber and bioaugmentation, and expanded rules for Belter, Earther, and Martian characters. This beautifully illustrated sourcebook opens new ways to play and build characters, and exciting new details on humanity’s homes. Sol System also offers a plethora of new adventure opportunities—political intrigue, spies, strange cults!—and sets the stage for the forthcoming Free Navy Conflict.
